installer’s frequently asked questions

1. MOUNTING THE LSP

The LSP can be mounted below, above, to the left or to the right of the existing circuit breaker panel. Approximately 17″x24″ of clear space is required to accommodate a LSP above or below a circuit breaker panel and approximately 17″x17″ of clear space is required to accommodate a LSP on either side of a circuit breaker panel (NOTE: modifications to the LSP’s conduit will be required in order to accommodate mounting the LSP to the left or right of the circuit breaker panel).

Yes, you can use junction boxes, combiner boxes, or additional hardware as needed to help accommodate your LSP installation so long as each component is utilized/installed in accordance with national, state and local code requirements.

Yes, the LSP can be installed with both surface mounted or flush mounted circuit breaker panels. Most surface mounted installation will require extension brackets for mounting, which are provided with your LSP.

Yes, you can use junction boxes, combiner boxes, or additional hardware as needed to help accommodate your LSP installation so long as each component is utilized/installed in accordance with national, state and local code requirements.

Lumin measures current and voltage through proprietary sensor boards and provides control through relays that are housed within the Lumin Smart Panel (LSP) enclosure.

The LSP comes with mounting hardware and mounting brackets (surface-mount installations) but installers will need the following tools to complete the installation process (mounting and wiring):

  • Drill
  • Manual knockout
  • Wire stripper
  • Wire nuts (for 6 AWG & 10 AWG wires)
  • Screwdriver
  • Tape measure
  • Level
  • Drywall saw (flush-mount installations)

Additional tools/equipment may be needed depending on the exact installation scenario.

2. WIRING THE LSP

Install the LSP’s Power Cable Harness by connecting the LSP’s white wire labeled “Neutral” to the existing neutral bar in the electrical panel; then connect the black LSP wire labeled “Line A” to a breaker located on phase A of the electrical panel; and then connect the red LSP wire labeled “Line B” to a breaker located on phase B of the electrical panel.

The LSP wires “Line A” and “Line B” can be connected to their respective breakers via double-tapping the breaker or via a three-way wire nut or via a new, unpopulated breaker if needed.

Select a circuit to connect to the LSP, turn it off and disconnect the load with a screwdriver. Then select a LSP wire labeled “Line # A” and connect it to the now vacant circuit breaker with a wire stripper and screwdriver. Next select the LSP wire with the corresponding line number and ending with B (labeled “Line # B”) and connect it to the disconnected load with a wire stripper and wire nut.

Ensure a tight connection is made between the two wires. Once the connection between the circuit and the LSP is completed you can turn the circuit breaker back on. Repeat these steps until all desired circuits are connected to the LSP.

The LSP is compatible with all circuit breakers rated up to 60 amps, regardless of the manufacturer or brand.

Extend the LSP wires labeled “Grid Neutral” (white) and “Grid Line” (black) and land them in the ATS (supply side) via the appropriate connection (lug, wire nut, line side tap, etc.).

If installing your LSP on a sub panel, then land the “Grid Neutral” and “Grid Line” wires into the main circuit breaker panel via the appropriate connection.

NOTE: For most Tesla Powerwall installations, Lumin recommends landing the “Grid Neutral” and “Grid Line” wires in the Tesla Gateway via a din rail and fuse holder (not provided) and then performing a line side tap on the supply side line above/before the ATS.

Lumin’s larger 200A CTs are designed to be installed on the existing circuit breaker panel’s main supply lines. Do this by connecting the CT labeled “Line A CT” to the corresponding LSP wire labeled “Line A CT.” Connect the CT labeled “Line B CT” to the corresponding LSP wire labeled “Line B CT.” Attach the CT labeled “Line A CT” to phase A of the main supply line and attach the CT labeled “Line B CT” to phase B of the main supply line.

Lumin’s smaller 50A CTs are designed to be installed on the PV generation/output line. Connect the CT labeled “Aux B CT” to the corresponding LSP wire labeled “Aux B CT.” Attach the CT labeled “Aux A CT” to phase A of the PV generation/output line and attach the CT labeled “Aux B CT” to phase B of the PV generation/output line. If no PV/solar generation line is present then you can attach the auxiliary CTs to an alternative line that adheres to the CTs 50 amp rating.

NOTE: Make sure that the marking “K” on the CT is facing toward the grid side.

While certainly possible, Lumin does not recommend modifying the LSP’s wires as doing so will void the product’s warranty and introduces the risk of damaging sensitive internal components.

3. REGISTERING THE LSP

To register/setup your LSP, please follow these four steps:

Step 1. Download the Lumin app from the Android or Apple app stores

[Click for Android][1] [Click for Apple][2]

Step 2. Open the Lumin app and create an account

Step 3. Once you’ve created a Lumin account click the “get started” button

Step 4. Follow the on-screen instructions to set up your LSP

Alternatively, if you are unable to download the Lumin app, you may register your LSP by following our manual setup steps:

Step 1. Once your LSP is properly installed and is powered on, connect to the LSP’s WiFi network using your computer, laptop, tablet or smartphone:

LSP Network Name: Lumin-[Unique ID] (ex. Lumin-888E8E333D) LSP Network Password: luminpass

Step 2. Once connected to the LSP’s WiFi network, open an internet browser and go to: [http://192.168.11.1][3]

Step 3. Once you’ve reached [http://192.168.11.1][4] click the “Start Setup” button to continue the account setup process

Step 4. Connect your LSP to the home’s WiFi network by selecting the name of the local WiFi network from the dropdown menu (or manually type it in) and entering the local WiFi network password

Step 5. Once your LSP is connected to the home’s WiFi network, make sure your connecting device is connected to the home’s local WiFi network

Step 6. Enter an e-mail address and password to create a Lumin account

Step 7. Log into your newly created Lumin account

To label your LSP’s lines/circuits, log into your Lumin account and follow these three steps:
